Implementation Reference

• src/utils/linked-api-tool.ts:36-58 (handler)

  The OperationTool base class implements the execute method, which is the core handler logic for running the 'nvFetchCompany' operation from the LinkedIn API.
  export abstract class OperationTool<TParams, TResult> extends LinkedApiTool<TParams, TResult> { public abstract readonly operationName: TOperationName; public override execute({ linkedapi, args, workflowTimeout, progressToken, }: { linkedapi: LinkedApi; args: TParams; workflowTimeout: number; progressToken?: string | number; }): Promise<TMappedResponse<TResult>> { const operation = linkedapi.operations.find( (operation) => operation.operationName === this.operationName, )! as Operation<TParams, TResult>; return executeWithProgress(this.progressCallback, operation, workflowTimeout, { params: args, progressToken, }); } }
• src/tools/nv-fetch-company.ts:7-136 (handler)

  The specific NvFetchCompanyTool class that configures the 'nv_fetch_company' tool with name, operationName, Zod schema, and MCP Tool definition.
  export class NvFetchCompanyTool extends OperationTool<TNvFetchCompanyParams, unknown> { public override readonly name = 'nv_fetch_company'; public override readonly operationName = OPERATION_NAME.nvFetchCompany; protected override readonly schema = z.object({ companyHashedUrl: z.string(), retrieveEmployees: z.boolean().optional().default(false), retrieveDMs: z.boolean().optional().default(false), employeeRetrievalConfig: z .object({ limit: z.number().min(1).max(500).optional(), filter: z .object({ firstName: z.string().optional(), lastName: z.string().optional(), positions: z.array(z.string()).optional(), locations: z.array(z.string()).optional(), industries: z.array(z.string()).optional(), schools: z.array(z.string()).optional(), yearsOfExperiences: z.array(z.string()).optional(), }) .optional(), }) .optional(), dmRetrievalConfig: z .object({ limit: z.number().min(1).max(20).optional(), }) .optional(), }); public override getTool(): Tool { return { name: this.name, description: 'Allows you to open a company page in Sales Navigator to retrieve its basic information (nv.openCompanyPage action).
